I'm trying to find somewhere I could buy flexible displays? I really have no idea if these are even that common or available....I know they exist. I'd like to be able to incorporate flexible LCDs into clothing. Don't need anything fancy. Monochrome would do, backlit would be nice.

the ones I have seen are by E-Ink. Their flexible displays are monochrome. They have two different types. One which sort of has the flexibility of a plastic sheet or heavy cardbord. These seem to be more or less identical to the regular e-reader displays, except that you can bend them to a certain degree.

The other type is really cool. Its super thin and can be roled or crumpled. However, this screen can only cycle through pre-programmed images.

Both are really hard to get your hands on, I would not be surprised if the second type had never been handed to third parties at all yet. (As its really cool, but as of now far from actually usefull ... well ... at least the last demo I have heard of, which is a while back.

Then there are a bunch of oleds floating around, where again you seem to have the same problems - they are either fairly stiff, or really flexible, but (and I dont know this as a fact, but I am quite sure) the really flexible ones probably only display pre-programmed sequences.

Also, while both sony and samsung build them, I am quite sure, that they dont actually own the patents to the technology. I have not however been able to figure out who actually does.

Anyway, again. Really hard to come by. I would not know how to get them...

You paint it onto fabric, if I recall, painting it onto dark fabric helps with the backlighting issue. Last I saw it, you could buy it in different colors, and each color required a different temperature to activate the color change. You can stick wire into the fabric and vary the resistance from the battery to get the different temperatures. It would be really difficult to attempt anything like video, but text is reasonable.

I don't know where you could buy it if you're interested, if anyone knows, lemme know.

I think you are thinking about "thermochromic paint"; you paint it on a surface, embed regular wire (or resistance wire), and as you pass current through the wire, the wire heats up, and the paint changes color. I did a google search for the stuff; it doesn't seem scarce (though it may be difficult to get - I didn't try to track any down).

I will not respond to Arduino help PM's from random forum users; if you have such a question, start a new topic thread.
